成员变量

/* struct usb_device_driver - identifies USB device driver to usbcore

* @name: The driver name should be unique among USB drivers,

* and should normally be the same as the module name.

* @probe: Called to see if the driver is willing to manage a particular

* device. If it is, probe returns zero and uses dev_set_drvdata()

* to associate driver-specific data with the device. If unwilling

* to manage the device, return a negative errno value.

* @disconnect: Called when the device is no longer accessible, usually

* because it has been (or is being) disconnected or the driver's

* module is being unloaded.

* @suspend: Called when the device is going to be suspended by the system.

* @resume: Called when the device is being resumed by the system.

* @drvwrap: Driver-model core structure wrapper.

* @supports_autosuspend: if set to 0, the USB core will not allow autosuspend

* for devices bound to this driver.

*

* USB drivers must provide all the fields listed above except drvwrap.
